Table I.
Regression line equations between normalized ANA (y) and normalized ureide content, malate content, and the ratio between malate and ureide content of ‘Jackson’ and ‘Biloxi’ nodules (x in each column, respectively)
Each equation is followed by its correlation coefficient (r2; in bold). Values were obtained from those given in Figures 2 to 5, normalized against their respective daily control values.
| Cultivar | Ureides | Malate | Malate/Ureides |
|---|---|---|---|
| ‘Jackson’ | y = − 0.132 × + 0.895 | y = 0.591 × + 0.258 | y = 0.261 × + 0.570 |
| r2 = 0.50 | r2 = 0.77 | r2 = 0.94 | |
| ‘Biloxi’ | y = − 0.129 × + 0.781 | y = 1.179 × − 0.384 | y = 0.639 × + 0.155 |
| r2 = 0.52 | r2 = 0.70 | r2 = 0.90 |
